This report is in the interest of posterity, and giving people with
similar bugs a search result. I don't need a fix because udev works
100%. However, I was unable to make devfs work at all in 2.6.2, and
2.6.3. I tried a lot of things, and it seemed to be locking when
creating tty's after hotplug events. In any case, especially usb the
hotplug stuff seemed to trigger process freezes. The init process would
suddenly stop. I SysRq worked fine, but as I was in a hurry, I did not
try to do more troubleshooting. I was never able to fully boot into a
2.6.2 or 2.6.3 kernel on my box with devfs enabled.
I recovered, and removed devfs, converted my gentoo install to udev, and
have had no trouble since.
thanks,

Can you provide any more details? I have been using hotplug with USB
devices daily on each of 2.6.2 through 2.6.4-rc1 without any freezes.
The only problem I've noticed is my non-hotplug issue with USB on my
notebook, using my wireless mouse. After a cycle of plug/unplug/plug
etc, the kernel starts spewing hundreds of messages a second about uhci
issues and makes the machine very slow. Doesn't fix until I remove the
uhci module. Has nothing to do with devfs or hotplug however. Both of
those work perfectly [for me] on four different machines.
